-Just as granum stack up to form part of the chloroplast, towers are made to form part of the solar energy plant.
-Stroma is to a cell, as solar panels in solar energy plants are to a city.
-Just as Stroma surrounds the granum to form chloroplasts, Solar panels surround towers to form solar energy plants.
-Together, Stroma and granum form chloroplasts in order to cause photosynthesis. Granum are made up of stacks of thykaloids and the stroma is a fluid that surrounds it.
